Investigation of mechanical properties of honeycomb composite parts made by VARTM and Hand Lay-up

In this article, VARTM method has introduced as a replacement way for the Hand Lay-up method of manufacturing composites with honeycomb core. Influence of resin into honeycomb core is the important challenge in production of honeycomb sandwich panels made by VARTM .This phenomena led to increasing weight, Solving of this problem and exhausting the resin from the holes high quality parts has produced. For this purpose, some parts manufactured by the Hand Lay-up method and the mechanical properties has compared. So the results represent that the parts manufactured by VARTM has less bubbles and better product and core strength quality, this led to the increasing of mechanical properties
